Another fun day in the trenches working on a client to control some embedded stuff.

I wasted about half a day dissecting log files, seeing the scale move the way it was supposed to when the machine was dispensing product, only to crash back down to around the starting value during the let the scale stabilize/last drop fall pause, and going WTF how is that happening.

The root cause turned out to be that the recently arrived box 2 is on a wobblier table, and/or has vibrateyer mechanicals, and/or a more vibration sensitive scale by a combined factor 15x!! vs box 1 which we'd done 99% of our dev/testing on.

Box1's peak scale jitter turned out to be ~50 during the setup phase (and typically only half that), which is small enough relative to the hardware's control elsewhere not to matter. Box 2 was regularly swinging 500-750, enough to totally fubar an operation dispensing only 375.

Adding insult to injury, it didn't help that the 2 cases I dissected in the logs both had due to apparently malicious coincidence a jitter peak that ended up reaching to roughly where the dispense operation was supposed to end up. If it ended up spiking to double and dropping I'd've been more likely to catch on without burning so much time.

On the whole it's been an interesting project, but there're days when I wish I hadn't found the effort to gnaw through the restraints when the alarm went off in the morning.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?
